Panasonic showcased its latest lines of 3D plasma, LED LCD , LCD, 3D Blu-ray and audio lines in an all-encompassing presentation in New York Tuesday that stressed across-the board connectivity as much as 3D capability.

The company provided a more detailed delineation of the VIERA Connect platform it announced at CES, explaining it as a cloud-based infrastructure of IPTV services it will make available to set-buyers that add interactivity – in the form of gaming, health/fitness and even out-of-market sports content streaming – to the earlier-established VIERA Cast connectivity platform. Many of the higher-end TVs are or will be VIERA Connect-capable, while some leader models will feature Easy IPTV – a limited basket of services from which viewers can access content, including Netflix, CinemaNow, Amazon Video On Demand, Pandora, Napster and Facebook. Skype capability also looms large in the product lineups.

Here are some highlights from the many introductions.

• Several new 3D plasma sets are due out in spring and summer that feature Neo Plasma technology, an improved version of Panasonic’s Neo PDP picture-enhancing technology.

The flagship VIERA Connect VT30 and GT30 series carry it, as well as a new fast-switching phosphor technology that the company says greatly minimizes crosstalk.

Also featured on all 3D sets is 2D-to-3D conversion capability allowing the viewer to either flatten or deepen the dimensionality of the image. In development for spring release are iPhone/iPad apps that will allow remote control of the sets.

VT30 models range downward in size from the 65-inch TC-P65VT30, due in May at $4,299.95. GT30 models range upward from 65 to 50 inches. Both series, as well as the VIERA Connect ST30 series, include 55- and 60-inch screen sizes, the new standard replacing earlier lines’ 54- and 58-inch sizes. The step-down S30 series of 42-, 50- and 60-inch screen sizes features Easy IPTV instead of VIERA Connect, and is not 3D.
